Correlation between ELISA rapid testing analysis and standard analysis for the quantification of the storage mycotoxin: Ochratoxin A (OTA)

A highly significant correlation was stated between ELISA rapid testing analysis and standard analysis (HPLC) for the quantification of the storage mycotoxin: Ochratoxin A (OTA).

Taking into account the safety and the quality of the end products of malting barley processing, there is a great interest in a rapid method for the detection of storage mycotoxins and gushing tendency in malting barley.

Rapid methods such as the ochratoxin A (OTA) Elisa test and gushing test on malting barley are promising but require further enhancement to be accepted for routine use by grain storage managers. Actual rapid methods enabling to detect fungal spoilage or quality damage from storage fungi in stored barley stocks, do not allow to screen a large number of samples in a short time, as required by the grain handling high flow rates at the loading or the unloading of grain stores.

This result is highlighting the correlation of OTA test with the results of a reference method (HPLC analysis). The correlation coefficient is highly significant for OTA extracted either from grain or from malt.
